Re: [Haskell-cafe] Haskell's "currying" versus Business Objects Gem Cutter's "burning"

In Haskell, currying can only be done on the last (rightmost) function arguments.

So

foo x y

can be curried as

foo x

but not as

foo ? y

where ? would be a "wilcard" for the x parameter.

The function flip can be used in two-argument functions, if you only have second argument but not the first:

function ??? arg2 -- this is what you mean flip function arg2 -- this is how you write it

So for example

let nums = flip map [1..10] nums (*2) [2,4,6,8,10,12,14,16,18,20] nums (subtract 1) [0,1,2,3,4,5,6,7,8,9]

For the general situation of N arguments, I don't think there are any predefined functions to help you. (After all, as N increases, the number of variations of argument order gets rather silly.) cheers D.
